IMPROVEMENT IN WHIFFLETREE-FASTENINGS.

Specification forming part of Letters Patent No. 127,822, dated J une11, 1812.

Specification describing an Improved Whiffletree-Fastening, invented byCHARLES AH- RENBECK, of N avasota, in the county of Grimes and State ofTexas.

The invention relates to the means by which single-trees are attached toa double-tree; and consists in hinging two hooks to a staple that isattached to one end of a double-tree, while .said hooks are heldtogether at their bases by a recessed and intermediate guard-plate.

In the accompanying drawing, Figure 1 is a top view of my invention, andFig. 2 is a section of same in line at w of Fig. 1.

A represents a double-tree, in which is inserted the legs I) b of astaple,B and a, a portion of a single-tree. This staple B is made ofiron, bent to form a rightan gle at two points, each equally distantfrom a different end of the rod. 0 is a holder, tubular at each end 0,and fitted on one of the legs of said staple, while it is recessed inthe middle, at C. D D are two hooks, each made preferably fiat on oneside and provided with an eye, d, in a plane at right angles to that inwhich the hooks By this construction the guard-piece 0 prevents thehooks from changing their relative position with respect to each other,while their freedom of motion upon the staple is not at all impaired.The ring of single-tree is first placed on one hook, carried up on itsshank, and then placed over the'end of the other hook, when the flatsides of both hooks are brought together. As both hooks are pivoted andmove together when jarred or jolted, no motion whatever can enable thesingle-tree to become separated from the double-tree. This separation ofthe single-tree from the double-tree often occurs when the ordinary hookconnection is used, or when a double one is employed but one of thehooks is rigid.

E is a stay piece, to whose eye 0 is attached the stay-chain whichconnects with axle.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is-

1. The whiffletree-fastening, consisting of the two hooks D D, holder 0c, and staple B, applied together and between the double and singletrees, as and for the purpose set forth.-

2. The two hooks D D, both pivoted to the staple of a double-tree, asand for the purpose described.

3. The stay piece E, hooks D D, and holder 0 0, all held to thedouble-tree by a single staple, B, as and for the purpose described.CHARLES AHRENBEGK. Witnesses:
